Office Action

§102
Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Claims 1-14 are pending in this application. Election/Restrictions Applicant’s election with traverse of Group I and a single disclosed species (Compound 294) in the reply filed on 04/03/2026 is acknowledged. PNG media_image1.png 117 675 media_image1.png Greyscale The traversal is on the ground(s) that “claim 15 of Group II has been cancelled and claims 11-14 are drawn to a method of treatment using the compound of Formula I”. The examiner disagrees with applicant’s argument. Applicants simply deleted one Group and introduced a new Group II. The amended claims 11-13 are drawn to a method of treatment and would replace the original Group II. Groups I-II lack unity of invention. The special technical feature of Group II involves a therapeutic technique and additional ingredients that is not present in the special technical feature of Group I. Furthermore, coexamination of the additional group would require search of subclasses unnecessary for the examination of the elected claims. Therefore, coexamination of the additional inventions would require a serious additional burden of search. The requirement is still deemed proper and is therefore made FINAL. Note that if Group I is found allowable, then the examiner would rejoin the method claims 11-13 of Group II. In order to expedite prosecution after rejoinder, the examine recommends that applicants delete “preventing” from claims 11-13 and also recite specific diseases in claims 11-12 as it was done in claim 13. The examiner searched the elected species and found no prior art. The search was expanded and stopped when a prior art was found. If the examiner finds another prior art after the response of this Office Action, the next Office Action will be Final. Note that the examiner recommends that applicants review their invention. Claim Rejections - 35 USC § 102 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. Claims 1-4 and 6-7 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Clapham et al. Tetrahedron Letters (2002), 43(31), 5407-5410. Cited reference teaches the following five prior art compounds that are the same as applicants when applicants Formula I has the following substituents: R1 = H; R2 = -CF3, -NO2, -OMe, -N(CH3)2; and R3 = piperidinyl. PNG media_image2.png 107 1483 media_image2.png Greyscale PNG media_image3.png 547 667 media_image3.png Greyscale PNG media_image4.png 620 1453 media_image4.png Greyscale PNG media_image5.png 659 1462 media_image5.png Greyscale PNG media_image6.png 660 1440 media_image6.png Greyscale PNG media_image7.png 649 1489 media_image7.png Greyscale Since said prior art compounds are the same as applicants, a 102(a)(1) rejection is proper. Objection Claims 5, 8-10 and 14 are objected to as being dependent upon a rejected base claim. Note that the search is ongoing. Information Disclosure Statement 6. Applicant’s Information Disclosure Statement, filed on 06/25/2025, 02/06/2025, 11/21/2024, 07/24/2024, 12/06/2023 and 12/05/2023 has been acknowledged. Please refer to Applicant’s copies of the 1449 submitted herewith. Conclusion 7.
